Jannik Sinner continued his winning streak on indoor hard courts, defeating Alexander Zverev in straight sets at the ATP Finals on Wednesday evening.
The Italian proved too strong for Zverev, defeating the German 6-4, 6-3 at the Inalpi Arena in Turin, Italy.
Sinner has become almost unbeatable on indoor hard courts, winning his last 28 matches on the surface.
Zverev, who beat Ben Shelton in his first round robin match, had seven break-point opportunities during the match, but was unable to convert any of these chances.
Zverev, who became distracted by a particular issue midway through the match, will need to beat Felix Auger-Aliassime on Friday to qualify for the semi-finals in Turin.
Alexander Zverev became distracted by a flickering LED board during his loss to Jannik Sinner
Jannik Sinner defeated Alexander Zverev with ease at the ATP Finals last night to continue his incredible form.
And Zverev was distracted while serving at 2-3 down during the second set as one of the LED boards surrounding the court suddenly turned off.
The board briefly continued to flicker on and off, and the German made his views clear as he issued a complaint to the umpire.
The official ultimately called somebody in to fix the issue, but Zverev was unable to hold his serve as Sinner won the game
Ultimately, this incident had little impact on the result or Sinner, who produced a serving masterclass to qualify for the ATP Finals semi-finals for a third consecutive year.
How will Alexander Zverev fare at the 2026 Australian Open?
Time is most certainly running out for Alexander Zverev to win a Grand Slam title during his career.
Zverev, a three-time Grand Slam finalist, last reached the final stage of a major at the 2025 Australian Open.
The German has the backhand and serve to win a major, but may need to adjust his forehand moving forward.
The forehand remains his weakest shot, while his backhand and serve are both shots that rank among the very best on the ATP Tour.
If the German can shore up his forehand, he will be a strong contender in Australia, no matter how Carlos Alcaraz or Jannik Sinner fare at the event.
